Question

Differtiate between scalar and vector physical quantity.write law of parallelogram of vector for addition of two vector.also explain the analytical method using above law far addition of two vector p and Q​

Answer 1

Difference Between Scalar and Vector Quantity. Scalar quantity refers to the quantity, which has only magnitude and no direction. On the other hand, vector quantity implies the physical quantity which comprises of both magnitude and direction. Physics is a science based on mathematics.

Answer 2

Answer:

hello,

1.--Scalar quantity refers to the quantity, which has only magnitude and no direction.

--On the other hand, vector quantity implies the physical quantity which comprises of both magnitude and direction.

2.--scaler is One-dimensional quantity .

-- vector is multi dimensional quantity.

3.-- scaler -It changes with the change in their magnitude.

--vector-it changes with the change in their direction or magnitude or both.

4.--scaler follows ordinary algebra rules.

--vector follows rules of vector algebra.

5.Last but not the least,

--scalar quantity can divide another scalar

--but this cannot be done in the case of a vector quantity.

i hope u got it.☺

If two vectors acting simultaneously at a point can be represented both in magnitude and direction by the adjacent sides of a parallelogram drawn from a point, then the resultant vector is represented both in magnitude and direction by the diagonal of the parallelogram passing through that point.
